This empirical study examines the relationships between ethical climates and organizational effectiveness moderated possibly by job satisfaction (JS), organizational commitment (OC), and organizational citizenship behavior (OCB). The sample consisted of 383 employees in four companies operating in South Korea. The study focused on desirable ethical climates, rather than all the nine types of Victor and Cullen, along with the firm characteristics. The results found that the impacts of desirable ethical climates are effective and positive, except on OC. Contrary to the antecedent research consequences, the impact of social responsibility climate on OC is negative. In addition, the results indicate that the firm's characteristics (size and nationality) differentiate their impacts on organizational effectiveness especially, on the factors of OC. Key words: Desirable ethical climate, firm characteristics, organizational effectiveness, organizational commitment.

The article focuses on the creation of the Societas Europaea (SE) in 2000, which is the business entity approved for European Union (EU) regulation. Topics include the simplified merger procedure created by SEs, the formation of SEs by public or private companies, and the shareholder created organization of the SE.*SOCIETAS Europeas *CORPORATIONS *CONSOLIDATION & merger of corporations *PROFESSIONAL corporations *BUSINESS enterprises *STOCKHOLDERS

European Union Soft Law: New Developments Concerning the Divide between Legally Binding Force and Legal Effects

The Modern Law Review

Mots clés : EU law, Soft law, Legal effects, Legally binding force, National regulatory authorities, General principles of law


The judgment in Polska Telefonia Cyfrowa sheds light on the legal effects of soft law instruments that the Court of Justice of the European Union (CJEU) will recognise, while distinguishing between their legally binding force and their legal or practical effects. European soft law is now often relied on in national courts, and can have an important impact on the rights and obligations of individuals. However, some of the goals of the Commission are only partly attainable due to the specific legal status of soft law instruments, and the current languages policy of the European Union. Given that soft law was not found to expressly impose obligations on individuals, the Court held that there was no requirement to publish it in all the official languages of the European Union. This has a negative impact on transparency and legal certainty, diminishing the role of soft law instruments in promoting such goals

There exist several characterizations of concavity for univariate functions. One of them states that a function is concave if and only if it has nonincreasing differences. This definition provides a natural generalization of concavity for multivariate functions called inframodularity. Inframodular transfers are defined and it is shown that a finite lottery is preferred to another by all expected utility maximizers with an inframodular utility if and only if the first lottery can be obtained from the second via a sequence of inframodular transfers. This result is a natural multivariate generalization of Rothschild and Stiglitz's construction based on mean preserving spreads.

Fee-for-service payments and consultation length in general practice: a workleisure trade-off model for French GPs

This article presents an adaptation of the labour supply model applied to the independent medical sector. First, we model simultaneous General Practitioner (GP) decisions on both the leisure time and the consultation length for two payment schemes: fixed fees and unregulated fees. The objective of this econometric study is to validate the theoretical prediction that doctors under unregulated fees may make choices about the length of patient consultations independent of their personal leisure decision. Indeed, according to our empirical results, the bidirectional link between leisure choice and consultation length ' verified with fixed fees ' does not hold any longer under unregulated fees. Our findings can be seen as a necessary but not a sufficient condition to legitimize unregulated fees in general practice. consultation duration general practitioners simultaneous equations work'leisure trade-off working time

Getting Explicit About the Implicit: A Taxonomy of Implicit Measures and Guide for Their Use in Organizational Research

Mots clés : Implicit measures, Indirect measures, Nonconscious processes, Automaticity


Accumulated evidence from social and cognitive psychology suggests that many behaviors are driven by processes operating outside of awareness, and an array of implicit measures to capture such processes have been developed. Despite their potential application, implicit measures have received relatively modest attention within the organizational sciences, due in part to barriers to entry and uncertainty about appropriate use of available measures. The current article is intended to serve as an implicit measurement “toolkit” for organizational scholars, and as such our goals are fourfold. First, we present theory critical to implicit measures, highlighting advantages of capturing implicit processes in organizational research. Second, we present a functional taxonomy of implicit measures (i.e., accessibility-based, association-based, and interpretation-based measures) and explicate assumptions and appropriate use of each. Third, we discuss key criteria to help researchers identify specific implicit measures most appropriate for their own work, including a discussion of principles for the psychometric validation of implicit measures. Fourth, we conclude by identifying avenues for impactful “next-generation” research within the organizational sciences that would benefit from the use of implicit measures

Mots clés : Alternative investments, Auctions, Diamonds, Gems, Hedonic regression, Luxury goods


This note examines the investment performance of diamonds andother gems (sapphires, rubies, and emeralds) over the period1999'2010, using a novel data set of auction transactions. Overour time frame, the annualized real USD returns for white and coloreddiamonds equaled 6.4% and 2.9%, respectively. Since 2003, theaverage returns have been 10.0%, 5.5%, and 6.8% for white diamonds,colored diamonds, and other gems, respectively. Bothwhite and colored diamonds outperformed stocks between 1999and 2010. Nevertheless, gem returns covary positively with stockreturns, underlining the importance of wealth-induced demandfor luxury consumption in collectibles markets

HEC Start up invitro ou la procréation assistée pour entreprises innovantes

F. ISELIN

Entreprendre & Innover

décembre 2012, vol. 4, n°16, pp.38-45


Lancé en 2011, le programme HEC Start-up InVitro, consiste à associer des entrepreneurs sans projets et des actifs sans porteurs. Les entrepreneurs sont des diplômes d'HEC, en fin de cursus ou anciens, et les actifs proviennent de partenaires, institution de recherches, PME ou ETI. Après une sélection rigoureuse, les participants se rencontrent, se choisissent et entrent dans un processus d'accompagnement de dix-huit mois. Les premiers résultats sont encourageants, puisque deux start-up, qui n'auraient pas vu le jour sans cette démarche proactive, ont été créées dès la première édition.
